ELECTRIC SHOCK, MOVING PARTS, and HOT PARTS hazards.
Consult symbols and related instructions below for necessary
actions to avoid the hazards.
1-2 Arc Welding Hazards
The symbols shown below are used throughout this
manual to call attention to and identify possible
hazards. When you see the symbol, watch out, and
follow the related instructions to avoid the hazard. The safety
information given below is only a summary of the more complete
safety information found in the Principal Safety Standards
section. Read and follow all Safety Standards.
Only qualified persons should install, operate, maintain,
and repair this equipment. A qualified person is defined
as one who, by possession of a recognized degree,
certificate, or professional standing, or who by extensive
knowledge, training and experience, has successfully
demonstrated ability to solve or resolve problems relating to the
subject matter, the work, or the project and has received safety
training to recognize and avoid the hazards involved.
During operation, keep everybody, especially children,
away.
ELECTRIC SHOCK can kill.
Touching live electrical parts can cause fatal
shocks or severe burns. The electrode and work
circuit is electrically live whenever the output is on.
The input power circuit and machine internal
circuits are also live when power is on. In semi-
automatic or automatic wire welding, the wire, wire
reel, drive roll housing, and all metal parts
touching the welding wire are electrically live.
Incorrectly installed or improperly grounded equipment is a
hazard.
l
Do not touch live electrical parts.
l
Wear dry, hole-free insulating gloves and body protection.
l
Insulate yourself from work and ground using dry insulating
mats or covers big enough to prevent any physical contact
with the work or ground.
l
Do not use AC weld output in damp, wet, or confined
spaces, or if there is a danger of falling.
l
Use AC output ONLY if required for the welding process.
l
If AC output is required, use remote output control if present
on unit.
l
Additional safety precautions are required when any of the
following electrically hazardous conditions are present: in
damp locations or while wearing wet clothing; on metal
structures such as floors, gratings, or scaffolds; when in
cramped positions such as sitting, kneeling, or lying; or
when there is a high risk of unavoidable or accidental
contact with the workpiece or ground. For these conditions,
use the following equipment in order presented: 1) a semi-
automatic DC constant voltage (wire) welder, 2) a DC manual
(stick) welder, or 3) an AC welder with reduced open-circuit
voltage. In most situations, use of a DC, constant voltage
wire welder is recommended. And, do not work alone!
l
Disconnect input power or stop engine before installing or
servicing this equipment. Lockout/tagout input power
according to OSHA 29 CFR 1910.147 (see Principal Safety
Standards).
l
Properly install, ground, and operate this equipments
according to its Owner's Manual and national, state, and
local codes.
l
Always verify the supply ground – check and be sure that
input power cord ground wire is properly connected to
ground terminal in disconnect box or that cord plug is
connected to a properly grounded receptacle outlet.
l
When making input connections, attach proper grounding
conductor first – double-check connections.
l
Keep cords dry, free of oil and grease, and protected from
hot metal and sparks.
l
Frequently inspect input power cord and ground conductor
for damage or bare wiring – replace immediately if damaged
– bare wiring can kill.
